The NTSB's narrative final · quoted from the NTSB record
The pilot reported that while approaching the airport, the engine lost power. The pilot switched from the left fuel tank to the right, and his attempts to restart the engine were unsuccessful. He initiated a forced landing to an open field. During the gear-up landing, the airplane spun around, slid through a drainage ditch and a fence before coming to rest. Inspection of the airplane revealed that less than a quart of fuel was present in the left fuel tank, and about 9 gallons of fuel was in the right fuel tank. No evidence of a mechanical failure or malfunction was found. The pilot stated that he had flown this route before and on the previous flight, he had refueled. On the day of the accident, the pilot elected not to refuel.
